`LanguageTree:parse` is recursive, and calls
`LanguageTree:for_each_child`, which is also recursive.
That means that, starting from the third level (child of child of root),
nodes will be parsed twice.
Which then means that if the tree is N layers deep, there will be ~2^N
parses even if the branching factor is 1.
Fixes: #25104
When an injection has not set include children, make sure not to add
the injection if no ranges are determined.
This could happen when there is an injection with a child that has the
same range as itself. e.g. consider this Makefile snippet
```make
foo:
$(VAR)
```
Line 2 has an injection for bash and a make variable reference. If
include-children isn't set (default), then there is no range on line 2
to inject since the variable reference needs to be excluded.
This caused the language tree to return an empty range, which the parser
now interprets to mean the full buffer. This caused makefiles to have
completely broken highlighting.
fix(treesitter): redraw added/removed injections properly
When injections are added or removed make sure to:
- invoke 'changedtree' callbacks for when new trees are added.
- invoke 'changedtree' callbacks for when trees are invalidated
- redraw regions when languagetree children are removed

Problem:
Codebase inconsistently binds vim.api onto a or api.
Solution:
Use api everywhere. a as an identifier is too short to have at the
module level.
Never return the changes an only notify them using the `on_changedtree`
callback.
It is not guaranteed for a plugin that it'll be the first one to call
`tree:parse()` and thus get the changes.
Closes#19915
Problem:
gen_vimdoc.py / lua2dox.lua does not support @defgroup or \defgroup
except for "api-foo" modules.
Solution:
Modify `gen_vimdoc.py` to look for section names based on `helptag_fmt`.
TODO:
- Support @module ?
https://github.com/LuaLS/lua-language-server/wiki/Annotations#module
Problem:
Help tags like vim.treesitter.language.add() are confusing because
`vim.treesitter.language` is (thankfully) not a user-facing module.
Solution:
Ignore the "fstem" when generating "treesitter" tags.
